Not meaning to be rude but it is really going to have to come down to you, the Gallo can carry more stuff (passengers and other stuff) but it's Sublight speed is terrible (not to mention it requires 6 times as many crew)

Personally I chose Action over Gallo, Action is faster and can hold enough for me, maybe not so great at hauling mats or passengers, but I use it to transport my groundhogs. As somebody said before me, it really depends on what kind of work you want to do.
